Anti-collision fence of road bridge

Abstract

The invention discloses an anti-collision protective fence for a road bridge, which comprises a connecting rod, the surface of the connecting rod is provided with a small hole for the connecting rod, and a supporting rod is connected inside the small hole of the connecting rod, and the surface of the supporting rod is fixed with a supporting rod A connecting block, and the surface of the supporting rod connecting block is connected with a rotating shaft connecting block, the end of the rotating shaft connecting block is fixed with a rotating shaft, and the surface of the rotating shaft is fixed with an anti-collision plate, the inner surface of the anti-collision plate is connected with a spring, and the spring passes through the spring clip The groove is connected with a support rod, the surface of the support rod is provided with a spring clamping groove, and the surface of the support rod is fixed with a support plate by a fixing screw, the lower end of the support rod is fixed with a base, and the inside of the base is connected with a screw. The anti-collision protection fence of the road bridge is easy to maintain and has a high safety factor, and the density of the protection rods on the guardrail can be adjusted according to requirements, and the occurrence of accidents such as vehicles rushing out of the bridge can be reduced.

Description

technical field [0001] The invention relates to the technical field of road bridges, in particular to an anti-collision protective fence for road bridges. Background technique [0002] Generally, when a car hits the guardrail of a road bridge, it is easy to roll off the guardrail and fall under the bridge due to the speed of the car, which is very dangerous. And the guardrail is generally an integral structure. When a part of the guardrail is damaged, it is very troublesome to repair. In addition, the general road and bridge guardrails cannot set the appropriate density of guardrail protection bars according to the needs of the road section. Aiming at these two problems, a kind of anti-collision protection bar for road bridges is proposed. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-collision protective fence of road bridge, to solve the above-mentioned general road bridge guardrail proposed in the above-mentioned bac...
